PIPE-STEM.

SPECIFICATION forming part of Letters Patent No. 226,750, dated April20, 1880. Application led August 21, 1879.

To all whom fit may concern Beit known that I, CHRISTIAN J. B. HIRscH,of Zumhrota, in the county of Goodhue and- State of Minnesota, haveinvented a new and Improved Pipe-Stem, of which the following is aspecification.

Figure l is a longitudinal central section of my improved pipe-stem,taken through the line :10, Fig. 5. r`Fig. 2 is a longitudinal sectionof the same, taken through the line y y, Figs. 3 and 4. Fig. 3 is a viewof the lower end of the cylinder. Fig. 4 is a view of the upper Fig. 5is a view ot' the inner end ofthe lower end piece.

The object of this invention is to furnish a short pipe-stem, whichshall have the effect of along one, cooling thc smoke and allowing thenicotine to condense from the smoke, and which may be easily cleaned.

The invention consists in a pipe-stem formed of the cylinder perforatedlongitudinally with a number of iiues connected at their ends in` pairs,and the perforated end pieces forming a continuous iiue from one end ofthe stem to the other, as hereinafter fully described.

A represents the middle part or cylinder of the stem, which hasscrew-holes formed in its ends to receive the screw formed upon theinner ends of the end pieces, B G. The outer end of the lower end piece,B, has a round tenon formed upon it to receive the cork for connectingit with the bowl, and the outer end of the upper end pieceC, has ascrew-hole formed in it to receive the mouth-piece.

The cylinder A is perforated with nine (more or less) longitudinalperforations, one passing through its center, a-nd the others beingarranged around its center. The central perforation o1' flue connectswith a hole passing through the upper end piece. The upper ends of theother ilues are connected in pairs by small chambers formed in the endof the cylinder A, which serve as return-hues.

At the lower end of the cylinderA the tlues are connected in. pairs bysmall chambers formed in the lower end piece, B, which serve to receivethe oil and condensed nicotine, and the end of the last or odd ue isconnected by an inclined hole with the hole passing out through thetenon of the said end piece, B, as shown in Figs. l and 2.

With this construction the various iiucs` form a continuous iue, so thatthe same effect is produced as it' a long stem were used.

With this construction, also, the stem may be readily taken apart andconveniently cleaned.

In using the stem the passage ofthe smoke is as follows: rIhe smoke fromthe bowl of the pipe passes into the hole l in the lower end piece, B,thence through the inclined' hole 2 to' the side hole, 3, through thecenter or main part A of the stem. The smoke then passes up and downsuccessively through the holes 3 4 5 6 7 8 9 l0. At thelower end ofthehole 10 the smoke passes through the inclined hole 11 into the lower endof the central hole, 12, and through the hole 13 in the upper end piece,C, into and through the mouth-piece.

Having thus described ,my invention, what I claim as new, and desire tosecure by Let-- ters Patent, is-

A pipe-stern consisting of three cylindrical pieces, one end adapted tot into pipe and the other to receive mouth-piece, while the intermediatepiece has around the central hole a circle of holes connected with eachother and with the central one, as shown and described.
